I am using SwiftLint to clean up my code formatting of the project. I met a File Name Violation warning. I tried many ways but I can't fix it.

Those are what I did:

  1. Create a class -> LoginPageViewController.
  2. Got a warning -> Length of class name should be between 3 and 20 characters long.
  3. Refactor the name of this class as LoginController everywhere.
  4. Run and got a warning: File Name Violation. Seems like the name still keeps the original one.
  5. Try to clean build folder, still doesn't work.
  6. Try to delete the file and recreate a new file with a totally different name, but the same warning with the same name LoginPageViewController is still showing.

The filename has already been changed to LoginController.

Please help me out. How can I fix it?

    Why have you created such a rule? 20 isn't that much for a filename when you want to include the type in the file namne, like viewController. Change the rule instead of your code. – Joakim Danielson Aug 14 '20 at 15:04

If for whatever reason you don't want to change the file name or the class name you can deactivate the "file_name"-rule in your .swiftlint.yml for defined files like this:

file_name: 
  excluded: ["MyClass1.swift", "MyClass2.swift", "MyClass3.swift"]

The file name remains as LoginPageViewController.swift. Rename it to LoginController.swift as the class.

Then, do Cmd + Shift + K to clean the build folder and try again.

Update: Seems this issue has occurred due to unsuccessful rename. Copy all the code in this file and delete this file. Create a new Swift file named LoginController and paste the copied code into it.

A simple solution to avoid this warning is to create an empty declaration for LoginPageViewController. Like this:

enum LoginPageViewController { }

To disable the warning in the any file, below code can be added in the first line of the file.

// swiftlint:disable:this file_name
